Interesting searchengineland article. Nice to hear that recovery is possible if you clean up spam...and this will be reflected in the next penguin update. When that is and what constitutes spam is still a good question.
Think the key is figuring out how google is discriminating between normal link building...and link building designed to take down a competitor. They seem REALLY sure that they don't have a problem and can tell the two apart...and this certainty maybe a clue to how Penguin works.
